According to the structural difference between the unidirectional and the bidirectional laminate ply, the traditional 3-D (three-dimensional) Hashin failure criteria and the corresponding stiffness degradation rules were amended for damage tolerance simulation analysis of plane woven-reinforced laminates. Based on 3-D finite element technique, a secondary development was carried out on ANSYS software platform, a cumulative damage model was established, and the simulation analysis program for damage tolerance analysis of plane woven-reinforced laminates with hole damage was developed by use of APDL (ANSYS Parametric Design Language). In order to study the influence of different hole diameters on damage tolerance of plane woven-reinforced laminates, two kinds of G803/BMP316 plane woven-reinforced laminates with different hole diameters were selected as the analysis and verification object, and residual tensile strength and damage extension process of the damaged laminates were predicted and analyzed in the simulation. The simulations results are close to the experimental results, and visually present the situation of damage extension in each ply. It provides an effective tool for the damage tolerance analysis of plane woven-reinforced laminates with hole damage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
